IMPROVEMENT IN SELF-ADJUSTING FILTERER AND CUT-OFF.

Specification forming part of Letters Patent No. 219,591, datedSeptember 16, 1879; application filed August 2, 1879.

To all whom it may concern Be it known that I, ALFRED W. MORGAN, ofIndianapolis, in the county of Marion and State of Indiana, haveinvented a new and useful Improved Self-Adjusting Filterer and Out-Off,of which the following is a specification, reference being bad to theaccompanying drawin gs.

The objectof my invention is to provide a selfoperating device forfiltering water for cisterns, by means of which the dirty water from aroof is allowed to pass off, the clean water allowed to pass through thefilterer, and the filterer adjusted after a rain so that no water canpass through it until the roof is first washed.

' spective view of my self-operating filtcrerand cut-ofi', showing itsposition when no water is passing through it. Fig. 2 is a top view ofthe same, showing it in position for water to pass through; and Fig. 3is an upright vertical section of the same, showing the generalarrangement of parts on the inside.

A represents the side of a building, or a board fastened thereto, towhich the filterboX B is secured by hinges T T at one of its verticalcorners, as shown in Figs. 2 and 3.

The hinges T T permit the filter-case B to swlng away from the wall, asshown in Fig. 1, or to be adjusted close to the wall, as shown in Fig.2. j

The arm F is soldered or otherwise made fast to the filter, as at b, andprojects back, and is provided with a bent arm, a, as shown, for thepurpose of forming a stop and preventing the filter from swinging toofar away from the building at its front side.

The cord at is attached to the arm F and passes over a sheave, G,attached to the board A, and is provided with a weight, H, which isdesigned to overbalance the bucket L at the front of the filter. Thecord gis secured to the filter at f, and passes over the sheave K, andis secured to the bucket Lifas shown, the operation of which will behereinafter fully described.

The filter B is divided into several compartments, S, V, U and N, by thesolid partitions R Q and per atejdi'partitions or bottoms P O, as shownlit-Fig. I

The bottom of the filter is provided with a spout, M, which leads fromthe chamber N to the cistern or reservoir, and the chamber V is providedwith two openings in the bottom, as follows, to wit: first, the openingJ, which is provided with a cap or plug, to be removed, when it becomesnecessary, to clean out any dirt or sediment that may accumulatetherein; and, second, the small opening 121, through which a smallquantity of water is permitted to leak into the bucket L, which willalso be described hereinafter.

The trough O is attached to the side of the board A or building, asshown, and is made adjustable backwardand forward to conduct a large orsmall quantity of water into the bucket L, as may be desired. The coverD is provided with an opening, E,at one end to permit the water to flowinto the chamber S.

The operation of my improved self-adjustable filter and cut-off is asfollows, to wit: The

board A or filter B is attached to the side of the house so that theopening E will come immediately under the end of the water-spout fromthe roof, and theopning or spout M immediately over the spout that leadsto the cistern or reservoir. When in this position the weight H and cord(1 overbalance the bucket L and draw the front side of the filter awayfrom the board A or building, as in Fig. 1,

clean water from the roof then flows through the opening E at the top ofthe filter into the chamber S and passes through theperforated bottom Pinto the chamber V below. The water then rises in the chamber U, and isfiltered in its passage through the movable perforated bottom 0 andsponge X until the chamber U is filled to the top of the partition B,over which the filtered Water runs in the direction of the arrow 6 intothe chamber N, from which it is conducted into the cistern or reservoirby means of the pipe M.

The clean water will thus continue to flow through the filter into thecistern until the water ceases to run from the roof and the water in thechambers S, V, and U has all run out through the hole on at the bottominto the bucket L, after which the water in the bucket L leaks outthrough the hole 5 until the Weight H over-balances the bucket, when thefilter is again moved to one side, as in Fig. 1, ready to have the nextshower wash off the roof before the filter adjusts itself for thepurpose of conducting the clean water to the cistern.

It will be seen from the foregoing that the water at all times when itis raining is leaking from the bucket through the hole 8, and at thesame time water is leaking from the chamber V through the hole on intothe bucket to keep up the required weight of water in the bucket; butwhen the water leaks out of the bucket the weight H predominates andcuts off or adjusts the filter.

The movable perforated plate 0 in the ch amber U is provided with a rod,w, for the purpose of drawing out the perforated bottom and thefiltering-sponge X when it is desired to do so.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a self-adj usting filterer and cut-off, the filter B, hinged tothe board A or building, and provided with an arm, F, combined with theweight H and bucket L, as and for the purpose specified.

2. In a self-adjusting filterer and cut-off, the

filter-box B, provided with the chambers S, V,

U, and N, as shown, combined with the stationary perforated bottom P,the movable perforated bottom O, and sponge X, as and for the purposespecified.

3. In a self-adj usting filterer and cut-off, the filter-box B, providedwith a drip-openil'lg, m, and hinged at T T to the board A or building,combined with the bucket L, also provided with a drip-hole, s,substantially as and for the purpose specified.

4. In combination with a swinging filter, B, operated by a weight, H, toswing open, and the water in the bucket L to swing shut, the adjustabletrough O, as and for the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALFRED W. MORGAN.
